SEPARATOR FOR T'WI STINGI-MACH INESAND THE LIKE.

To ctZZ whom, it may concern:

Be it known that I, JOHN A. JAMIESON, a subject of the King of. Great Britain, residing in Harrison, Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Separators for Twisting-Machines and the Like; and I do hereby declare the following to be a full,-

clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make. and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to separators for twisting-machines, spinning-machines, and the like. These devices are blades which when in operative position partition off the various fields of winding from each other for purposes well known to those skilled in the art, and with the object of having access to the various parts they are made movable out of their operative positions, either individu ally or in groups, by being pivotally mounted. I iind in practice that it is anadvantage in point of convenience and the saving of time to have the separators arranged for movement vertically as well as pivotally.

One object of my invention is therefore to so construct and arrange the various parts as to provide for such vertical movability of the separators.

Another object is to provide means which will automatically move the separators to their normal or operative position should they be inadvertently left after starting the machine in an abnormal position, (to which they have been vertically moved.) I

Other objects will be made to appear in the detailed description to follow.

My invention will be found fully illustrated in the accompanying drawings, in which- Figure 1 is a front View of so much of a spinning machine provided with my im provements as is necessary to illustrate the invention. Fig. 2 is a sectional view on line is 9c in Fig. 1 looking toward the right. Fig. 3 is a detail view illustrating one of the separators in plan, and Fig. 4 is a detail view illustrating a slight modification.

ring-plates e, and f a spindle, all constructed and arranged substantially as usual.

Penetrating thebolster and lower rails are vertical shafts g+say three in number-to each section of the machine. They aremovable vertically, and one of them, preferably the middle one, has two notches h and L- and is engaged by the upper overhanging end of a stout plate-spring j, which is suitably secured to rail 0 in such manner that if either notch coincides with the end of the spring the latter will take into the same and'support said shaftand also the other two shafts .g and certain other parts, as will appear later on.

76 is a bow or presser piece attached to spring and projecting upwardly convenient to the reach of the tenders hand or knee. f Each shaft-g is surmounted by a cross-arm Z, rigidly fixed thereto and extending-transversely of'themachine. These are preferably braced orbound together, so as to make of them and shafts g a vertically-movable structure by a bar m, having brackets n, which are bolted to the cross-arms. I may, however, state that this bar m and brackets n can be left off, if so desired. On each shaft is coiled a spring 0, which rests on the bolsterrail and serves as a buffer for the corresponding cross-arm when the structure falls to its lowest limit, Fig. 2.

The front end of each cross-arm'has an we tension p, and this receives the bifurcated portion of a bracket 1", which is pivoted to the cross-arm by a bolt 8, saidbracket being thus removable upon removing the bolt. The several brackets are penetrated by a rod i, being thusadapted to be moved togetherlon their pivots. In Fig. 4 rod tis shown slightly farther removed from the pivots of the brackets than in Figs. 1 and 2, so that in the normal or working position of the parts it will comeabout opposite the lowest limit of movement of the ring-plates 6, serving thus as a guard for the lower flanges ofthe bobbins, if bobbins instead of cops are used. The bar m, it will be noticed, serves as a guard for the spindle-whirls u when the structure carrying the separators is in its lowest position and theseparators turned down. I do not wish, however, to be limited to the positions of this bar m and rod t.

The separators are adapted, as shown in the drawings, to swing forward and down from their working position to the idle position. On a view to Fig.2 it will be seen that each separator is (in the idle position) not only entirely out of the area occupied by it i is thus afforded (when the separators are in their idle position) absolute clearance for cleaning the separators while the machine is running.

On rod t between the brackets 1" are other brackets 12, secured thereto by set-screws o. This arrangement permits lateral adjustment of the brackets v and, according as it is required, varying the number thereof. All the brackets are preferably rounded on the edges, (see Fig. 3,) so as to minimize fuzzing upon a thread breaking and lashing against them. Each bracket 7 and 1) carries a blade M, which is of such vertical dimension that when in operative position it extends about as high as the spindles and below the rings, thus perfectly isolating each winding unit from its neighbor and preventing the yarn ends from fuzzing or blackening the material on the neighboring spindles. The blade is preferably rectangular. The blades are all substantially alike except that those on brackets 1" are extended downwardly more than the others, so as to afford a rest for the whole series of blades (which owing to the arrangement above described are pivotally movable together) on the corresponding cross-arms, in which the brackets 1" may participate by having their pivoted ends when they are vertical abut squarely against the tops of the crossarms. (See Fig. 2.)

From the foregoing it will be apparent that the structure, comprising shafts g, cross-arms Z, bar m, the blades, and their interconnecting mechanism, is movable bodily from the normal or working position-i. 6., where spring j engages notch hto a position either above or below the normal position'L. 6., where spring j engages notch i or where the structure is supported on springs 0. Thus clear access to the work can be had for whatever purpose either from above or from below the blades. They can also be moved outwardly and forwardly on their pivots in the dottedline position in Fig. 2 for cleaning, &c. The structure is raised by simply lifting it manually. It can be made to fall by gravity by pressing on how k, so that the spring is thrown out of engagement with either of the notches h i.

In order to bring the structure above referred to to the normal or working position should it be left above or below that position after the machine is started running, I provide the following mechanism: The middle cross-arm Zis formed with an extension to and is penetrated by a rod 90, movable vertically therein This rod extends through the cor responding ring-plate e and then has its upper end bent over, as at y, being held against turning in the plate by a pin .2. The lower end of the rod is threaded, as at 1, and car ries a nut or nuts 2. If the said structure has been left below the normal or working position, when the machine starts the upward movement of the ring-rail will raise rod m, the nuts 2 on which will engage extension w and lift the structure far enough so that spring can engage in notch h. If the structure is above the working position, the ring rail will engage extension u) and push the structure downwardly, the peculiar overhang of the spring permitting its disengagement from notch i at this time and the structure falling until it rests on the spiral springs 0. The ring-rail, rod ac, and nuts 2 therefore serve as a moving part for bringing said structure to its working position if at any time it has been left out of that position.

Besides having rounded edges, as hereinbefore stated, it will be observed that the brackets r are relatively wide. Each bracket r thus presents a broad surface, preferably rounded, so that the separator, in effect, on the one hand, not only confines the lashing of the thread, but, on the other hand, offers a broad face for the thread to lash against, and thus materially reduces fuzzing.
